Copy code from master: add assertions on start and value, replace 'i'
iterator with 'end' pointer for the loop stop condition.
_PyUnicode_FastFill(): fix type of 'data', it must not be constant,
since data is modified by FILL().
Regression introduced in e3ce695 and 25b804a, where the old parameter
update_tryorder to _synthesize was first ignored, then given the opposite
value in the attempt to fix bpo-31014.

Fix str.format(), float.__format__() and complex.__format__() methods
for non-ASCII decimal point when using the "n" formatter.
Rewrite _PyUnicode_InsertThousandsGrouping(): it now requires
a _PyUnicodeWriter object for the buffer and a Python str object
for digits.

test_embed.InitConfigTests now gets the expected configuration from
a child process run with -S to not run the site module.

The "-I" command line option (run Python in isolated mode) is now
also copied by the multiprocessing and distutils modules when
spawning child processes. Previously, only -E and -s options (enabled
by -I) were copied.
subprocess._args_from_interpreter_flags() now copies the -I flag.

* bpo-35189: Fix eintr_tester.py (GH-10637)
Call setitimer() before each test method, instead of once per test
case, to ensure that signals are sent in each test method.
Previously, only the first method of a testcase class got signals.
Changes:
* Replace setUpClass() with setUp() and replace tearDownClass() with
tearDown().
* tearDown() now ensures that at least one signal has been sent.
* Replace support.run_unittest() with unittest.main() which has
a nicer CLI and automatically discover test cases.
(cherry picked from commit aac1f81eef)
* bpo-35189: Retry fnctl calls on EINTR (GH-10413)
Modify the following fnctl function to retry if interrupted by a signal
(EINTR): flock, lockf, fnctl.

bpo-34523, bpo-35290: C locale coercion now resets the Python
internal "force ASCII" mode. This change fix the filesystem encoding
on FreeBSD CURRENT, which has a new "C.UTF-8" locale, when
the UTF-8 mode is disabled.
Add _Py_ResetForceASCII(): _Py_SetLocaleFromEnv() now calls it.
(cherry picked from commit 353933e712)
* bpo-9263: _PyObject_Dump() detects freed memory (GH-10061)
_PyObject_Dump() now uses an heuristic to check if the object memory
has been freed: log "<freed object>" in that case.
The heuristic rely on the debug hooks on Python memory allocators
which fills the memory with DEADBYTE (0xDB) when memory is
deallocated. Use PYTHONMALLOC=debug to always enable these debug
hooks.
(cherry picked from commit 82af0b63b0)
* bpo-9263: Fix _PyObject_Dump() for freed object (#10661)
If _PyObject_Dump() detects that the object is freed, don't try to
dump it (exit immediately).
Enhance also _PyObject_IsFreed(): it now detects if the pointer
itself looks like freed memory.
(cherry picked from commit 2cf5d32fd9)
os_read_impl() now also truncates the size to _PY_READ_MAX
on macOS, to avoid to allocate a larger buffer even if _Py_read() is
limited to _PY_READ_MAX bytes (ex: INT_MAX on macOS).

locale.localeconv() now sets temporarily the LC_CTYPE locale to the
LC_MONETARY locale if the two locales are different and monetary
strings are non-ASCII. This temporary change affects other threads.
Changes:
* locale.localeconv() can now set LC_CTYPE to LC_MONETARY to decode
monetary fields.
* Add LocaleInfo.grouping_buffer: copy localeconv() grouping string
since it can be replaced anytime if a different thread calls
localeconv().

Fixes assertion failures in _datetimemodule.c
introduced in the previous fix (see bpo-31752).
Rather of trying to handle an int subclass as exact int,
let it to use overridden special methods, but check the
result of divmod().

* The _PySys_EndInit() function now copies the
config->module_search_path list, so config is longer modified when
sys.path is updated.
* config->warnoptions list and config->xoptions dict are also copied
* test_embed: InitConfigTests now also tests
main_config['module_search_path']
* Fix _Py_InitializeMainInterpreter(): don't use config->warnoptions
but sys.warnoptions to decide if the warnings module should
be imported at startup.

test_embed.InitConfigTests tests more configuration variables.
Changes:
* InitConfigTests tests more core configuration variables:
* base_exec_prefix
* base_prefix
* exec_prefix
* home
* module_search_path_env
* prefix
* "_testembed init_from_config" tests more variables:
* argv
* warnoptions
* xoptions
* Py_HasFileSystemDefaultEncoding value is no longer tested since it
depends on the LC_CTYPE locale and the platform.
* InitConfigTests: add check_global_config(), check_core_config() and
check_main_config() subfunctions to cleanup the code. Move also
constants at the class level (ex: COPY_MAIN_CONFIG).
* Use more macros in _PyCoreConfig_AsDict() and
_PyMainInterpreterConfig_AsDict() to reduce code duplication.
* Other minor cleanups.
(cherry picked from commit 01de89cb59)
* Add C functions:
* _Py_GetGlobalVariablesAsDict()
* _PyCoreConfig_AsDict()
* _PyMainInterpreterConfig_AsDict()
* Add new _testcapi methods:
* get_global_config()
* get_core_config()
* get_main_config()
* test.pythoninfo: get global, core and main configuration
* _testembed now serializes global, core and main configurations
using JSON to reuse _Py_GetGlobalVariablesAsDict(),
_PyCoreConfig_AsDict() and _PyMainInterpreterConfig_AsDict(),
rather than duplicating code.
* test_embed.InitConfigTests now test much more configuration
variables
